Ad. t-series
The Adûnaic t-series of homorganic consonants included the dentals consonants and the liquids [r] and [l], which Tolkien often classified with dentals. They were mostly survivals of the Primitive Adûnaic t-series, as well as the primitive palatal c-series which largely became the sibilants [s] or [z] (SD/418).
